A; Referring to the drawings, A represents -i a rall havlng a standard cross section, and

B a tie supporting the rail.

Disposed upon the tie, is a bed plate 5, preferably a rolled shape and substantially rhomboidal in form, said plate preferably extending the entire width of the tie so as to' form an extendedplatesupport and thus-` `prevent cutting and crushing of inferior wood ties. The bed plateis provided with spaced pairs of upstanding ianges 6 and 7,

Iof equal height, the outer flanges 6 being i The bed plate `5 is permanently attached Kto the cross tie vby means of screw spikes 8 whichnpass through suitable openings 9 formed in the bed plate `between the anges 6 and 7, eachscrews'pike being formed intermediate its ends with an annular shoulder against the bed `plate -around the adjacent opening' 9.

The rail A` is held in lplaceY between the Vinner abutments 7 for lateral andvertical adjustment bv means of rail engaging mem- .bers'11. Eachrail engaging member is provided with a tapered wedge-shaped portion 12 adapted to bear against the inner face of theadjacent abutment 7 and an inwardly extending clamping lip 13 which bears against the upper surface of the base Hange of the rail and jthe'web thereof, as best shown in FigjQ` of the drawings: `Each `rail engaging Ymember is also provided `with a laterally extending web 14, the lower face .H15 of which is smooth and unobstructed for 'engagement with the upper facesof the adjacent anges 6 and Zor for contactwith In the accompanying drawings: y `Figure 1 is a perspective-view ofia rail suitable side shims V16 when the rail "is ad- `j usted vertically with respect to the chair `for surface,J ovgrhangng 1li of each Patented sepa a4, 191e;

equal height, a screw spike disposed between the flanges of each pair, rail engaging members having inwardly extending rail clamping lips and provided with tapered wedgej shaped portions for contact with the inner slotted rail engaging members adapted to bear against the upperf faces of the fianges or against side shims for holding a rail in different positions of lateral and vertical ad justment with respect to the bed plate, primary fastening devices for securing the bed` plate to a cross tie, and secondary fastening devices extending through the slots in the rail engaging members and engaging the primary fastening devices and said rail engaging members for positively preventing accidental displacement of the rail engaging members after the latterrhave been adjusted to shift the rail.`

8. A lrail chair including a bed p'late having spaced pairs of upstanding abutments, rail engaging members adapted to bear against the upper faces cf the abutments or j against side shims for holding a rail in different positions of lateral and' vertical adjustment, primary fastening devices for permanently Ysecuring the bed plate to a cross Gopies o1.' this patent may be obtained for tie, and secondary fastening devices forming a protection for the primary fastening devices and co-acting with said rail engaging members. j

9. A rail chair including a bed plate havingspaced pairs of upstanding flanges, the inner flange of each pair constituting an abutment, rail engaging members adapted to bear against the upper faces of the anges or against `side shims and provided with slots, primary fastening devices disposed be- ;tween the pairs of flanges, and secondary fastening devices having depending portions extending through the slots in the rail engaging members and between the adjacent j fianges for engagement with the primary fastening devices.

10. A rail chair including a bed plate having spaced pairs of up'standing flanges of equal height, the inner flange of each pair constituting an abutment, rail engaging l members adapted to bear against the upper faces of the flanges or against side shims and provided with slots, primary fastening devices disposed between the airs of iianges, secondary fastening devices extending through the slots in the rail engaging members and between adjacent flanges for engagement with the primary fastening devices, said secondary fastening devices being provided with angular heads and laterally extending flanges, and yieldable means interposed between the flanges of the secondary fastening devices and the adjacent rail engaging members. 1 Intestimony whereof I affix my signature in presence of two witnesses. j
